我試圖為我的django網(wǎng)絡(luò)應(yīng)用程序用戶的個(gè)人資料詳細(xì)信息構(gòu)建一個(gè)模型，例如：class UserDetails(models.Model):    user = models.ForeignKey(User, on_delete=models.SET_NULL, null=True)    profilePicture = models.ImageField(blank = True, upload_to='profile_pics/'+self.user.id+'/')    country = models.CharField(max_length = 50, default='India')    gender = models.CharField(max_length=10, default='NA')    birthday = models.DateField(default=datetime.now())    phone = models.CharField(max_length=15)我在上面的模型中有一個(gè)圖像字段，我想將傳入的圖像上傳到我的媒體存儲(chǔ)路徑中的路徑。我試圖通過將圖像字段的屬性指定為 來做到這一點(diǎn)。我正在使用 AWS S3 進(jìn)行媒體存儲(chǔ)，并且我已將設(shè)置中的必要設(shè)置設(shè)為：profile_pics/<id of the user whose profile is being set up>/upload_toupload_to = 'profile_pics/'+self.user.id+'/'AWS_ACCESS_KEY_ID = 'myaccesskeyid'AWS_SECRET_ACCESS_KEY = 'mysecretaccesskey'AWS_STORAGE_BUCKET_NAME = 'mybucketname'AWS_S3_FILE_OVERWRITE = FalseAWS_DEFAULT_ACL = NoneDEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'當(dāng)我嘗試進(jìn)行遷移時(shí)，我收到以下錯(cuò)誤：Traceback (most recent call last):  File "manage.py", line 21, in <module>    main()  File "manage.py", line 17, in main    execute_from_command_line(sys.argv)請(qǐng)幫助我將圖像上傳到此模型的默認(rèn)路徑設(shè)置為 。profile_pics/<id of the user whose profile is being set up>/
